Replacing iniparser in mod_tile is something I would like to help with/do, I had a talk with someone actually involved with development a while back who said this would not be too hard.

Some unanswered questions remain though, would switching config file format be an option (e.g. to something like YAML), and what library to replace iniparser with (I found a few I think when I looked previously, but I don't do too much c/c++ development so I had trouble telling between them).

I have seen that before, but could not get it working in JOSM, however, upon trying again, it now works :) Thank you for putting it together, I should be able to get quite a lot of postcode coverage using it.

I had a try at using the JOSM reverter plugin to fix things, however its very hard to tell if its working, as the above changeset is one of many that makes "unintended" changes to the map... If you are really stuck, and have discussed this with Danzelot, I can go ahead and try to revert/fix the problem changesets.

Love it, this is something I have been very interested in. The point at which I think it gets really interesting, is if you have a multitouch table, I can imagine drawing out buildings with multiple fingers from one hand, while moving the map with the other... The scope for multiple people editing the same area of the map could also be quite interesting with touch table devices.
